As promised the README.md at Subject level explaining the different data models is automated, and therefore there is no need to be contributed by the contributors. See an example here for the weather subject
Thus, the README.md is based on the data models and their descriptions, linking to the current contributors
Soon the README.md for the domain will be also automated.
Best
if you are browsing the repository you can realise that now there are several data models ended with the term ‘_incubated’.
This suffix denotes that there will be ‘soon’ a new data model.
The readme in the folder points to the repository where this data model is being created.
Once finished (all the docs, examples, etc) the _incubated suffix will be removed and the data model will be fully included into the data models.
some examples:
BuildingType_incubated(published 30-11-21)
PhreaticObserved_incubated (published 31-5-2021)
This is the first survey to the USERS of the Smart Data Models. We want to know what is more important to you and try to prioritize our efforts. This is an agile initiative, therefore we will take into very consideration your comments. Your survey is anonymous although if you wish you can include your email in comments and we will contact you regarding your comments.
You can answer it here.
Soon there will be another survey for the CONTRIBUTORS.
In order to provide a more transparent and participative approach to the creation and maintenance of data models, here you can see the three stages for a usual data model to be part of the official list of data models.
1.- Pending is the ‘wild’ zone where developers share their thoughts and create their data models. When finished (ready) they can create a PR on the right Subject repository.
2.- Harmonization is the repository for those new accepted models while they are fine-tuned or completed
3.- Subject means the repository in which the data model is officially published. Once there they are versioned when necessary.
| Pending | Harmonization | Subject | |
| Control of contributions | No | Yes | Yes |
| Scripts for checking | No | Yes (specific) | Yes (only acceptance and on update) |
| Code inside json schema | No | Harmonizing | Local standard
Global standard |
| Versioning | No | No | Yes |
| Managed | Each contributor | Contributor + SDM control | SDM control |
| In domain | No | No | Yes |
| Accept issues | Yes but not managed | Yes | Yes (Here the open ones) |
| First Access | Anyone |

SDM: Smart Data Models initiative
The European open data portal is possibly the biggest open data portal in the world with more than one million free datasets coming from 36 countries.
One of the mechanisms to access its data is the use of the standard of DCAT-AP standard 2.0 which defines its catalogue of resources.
In the repository pending there are two data models, in progress to connect a dataset and a distribution as an additional resource by using NGSI. The idea is to create a script to map this resource into NGSI.
Every data model has a directory with examples of the payloads (json and jsonld) in key-values and normalized formats.
But it also includes examples of csv that it could help to connect the data models for other platforms.
Now, these examples are re-created automatically once a day.
The naming convention for these examples are the same name of the original payload plus a .csv suffix.
An example for the Battery data model examples.
Best.
In the upper menu (option Search descriptions) there is a searchable database of the descriptions for all the properties across the different data models.
Try it out here.
This DDBB is updated daily.
This data model, node, is not officially approved but is on the path for becoming a resource for simulation a node inside a digital twin model (See this video) receiving the measures from an array of sensors controlling different properties and to provide these data to several other nodes which can be connected to.
Remember that incubated repository is devoted to the design and test before submitting officially to the Smart Data Models initiative.
You can claim access to this repository in the issue form option access to the incubated repository.
In order to align the data model for museum inside the subject of PointOf Interest with the Schema.org regarding the opening hours specification, it has been modified to make it compliant with it.
in fact, this translation of schema.org it has become part of the common shared elements of the data models available in the section DateTime-commons at the common-schema.json.
Every subject had a file named CONTRIBUTORS.md which compiles all contributors to the different data models in this subject. However, from the point of view of the management, it was not a structured format. Due to this, it is going to be replaced with a new file named CONTRIBUTORS.yaml with the same info but structured so we could manage properly and answer questions like:
Now there is also a field for allocating comments.
The format is friendly enough to be simply edited but at the same time, it can be automatically processed.
Next week CONTRIBUTORS.md will be removed from the different repos.
